  • Full solution – IQML provides easy-to-use access to IQFeed’s entire data-set within Matlab. Only the core Matlab and IQFeed’s client app are required – no additional toolbox or component is required.
  • Stability – IQML has been extensively tested. It is rock solid.
  • Inexpensive – IQML provides excellent value compared to other connectors of its kind or to the amount of time that would be needed to develop a similar robust connector from scratch. A fully-functional free trial version is available (see below).
  • Easy to use – Users can access IQFeed’s data by simple Matlab commands, without need for any Matlab programming. IQML simplifies the IQFeed API in a very easy-to-use yet powerful interface that can be used by any Matlab user, novice or advanced.
  • Extensive IQFeed functionality – See full functionality list below
  • Novice and advanced users – Users can use easy-to-use Matlab commands, to access IQFeed’s data. Minimal or no programming is required to access this data.
  • Blocking and non-blocking (streaming) modes – Users can receive IQFeed data both synchronously (waiting for data to arrive with optional timeout), and asynchronously (streaming data in the background).
  • Settable market alerts – Users can define custom alerts on streaming news/quotes/interval-bars/regional-updates, which can be reported in various ways (popup window, console message, email, text (SMS) message, or Matlab callback function).
  • User callbacks – Users can attach Matlab code (callbacks) to IQFeed messages. For example, this enables adding an entry in an Excel file, or sending an email, whenever a stock reaches a certain price or trade volume (also note the related alerts functionality).
  • Compatibility – IQML works on all platforms where IQFeed runs (Windows, Mac OS, Linux), using practically any combination of IQFeed and Matlab release of the past decade (details).
  • Security – IQML transmits information only to IQFeed, so your trading information are as safe as your own computer.
  • Compilable – IQML can be compiled into a standalone executable or program component, running as an integral part of your deployed program.
  • Performance – IQML is optimized for performance, providing fast and responsive connectivity. While Matlab as a platform is not well-suited for HFT, IQML enables receiving hundreds of streaming quotes or other IQFeed messages per second, with message latencies as low as 1ms and parallelization supported.
  • Development – IQML was developed by an acknowledged Matlab expert, who wrote the reference textbooks on Matlab-Java connectivity and Matlab performance, as well as the acclaimed IB-Matlab connector (Matlab connector to Interactive Brokers). IQML is continuously improved and maintained.
  • Support – Custom development and ongoing support is available directly from the developer, with extremely fast response times.
  • Documentation – Extensive and comprehensive documentation, with numerous code examples and usage tips (see below).
  • Backtesting – IQML does not include backtesting functionality. IQML’s author (Yair Altman) has extensive experience in developing complete backtesting and real-time trading applications. We will be happy to develop a new application based on your specifications, or to integrate IQML into your existing application, under a consulting contract.

No other solution provides this rich set of features. Don’t take our word for it – download the free trial and check for yourself. You will not be disappointed. If you have any question, don’t hesitate to email us at for additional information.

Requirements and compatibility

IQML is a Matlab connector to IQFeed, so it naturally requires the user to have both, specifically:
Mathworks partner

  • a locally-installed Matlab (no toolbox is required) or MCR (for a compiled application)
  • a locally-installed IQFeed client (IQConnect)
  • an active IQFeed data account


  • Platforms: IQML works on all platforms on which IQFeed runs: Windows, Linux, Mac OS.
  • IQFeed: IQML works with all recent IQFeed releases, including the latest IQFeed API (6.2).
  • Matlab: IQML works on all Matlab releases since 2008, including the latest release (R2023a).

  1. Each individual license (Commercial, Academic, or Bundle) is limited to a single user on a single physical computer. Running on multiple computers requires multiple individual licenses, or one of the other license types (Site, Deployment or Development).
  2. The Academic license is available to currently-active members of a degree-granting academic institution (students or faculty) who use an academic email account.
  3. The support package is discounted to support IB-Matlab and IQML usage, in addition to free installation support. One support package per customer.
    Support via email/chat/phone, Sun-Fri. Guaranteed response within 1 business day, typical response within 1 hour during EST/GMT business hours.
    Package expires 12 months after its purchase. Additional support beyond the purchased package can be purchased at regular consulting rate.
  4. IQML can be compiled and deployed using the Matlab Compiler. Each computer running a compiled IQML requires an IQML license (just like a non-compiled IQML that runs in Matlab), unless you get a group license (Site, Deployment, or Development). In other words, for your deployed computers you have a choice of either buying individual licenses (separately for each deployed computer), or a group license which does not require dedicated license activations.
  5. License renewal can be to any license type and any duration, not necessarily the same as the original license purchase, as per the pricing table at the time of renewal.
  6. Each Standard license can be upgraded to a Professional license for the price difference plus a $50 change fee. Contact us to get the payment link.
  7. License cost includes free support by email for installation problems, and unlimited free product upgrades during the license term. Prices are subject to change from time to time.
    Payment is processed by PayPal. A PayPal account is not required; all major credit cards are accepted. Contact us if you wish to pay via wire (bank) transfer.
    Secure payment via PayPal
